GEM-SETTING.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed February 15, 1919. Serial No. 277,285.

T 0 all whom it may concern Be it known that 1, MAX BAUMAN, a citizen ofthe United States, and a resident of the city of New York, borough ofManhattan,'in the county and State of New York, have invented a new andImproved Gem- Setting, of which the following is a descrip tion.

My invention relates to gem settings of jewelry, andmore particularly isintended for embodiment in finger rings. The invention is especiallyuseful for setting'gems having a small area or a limited spread as it istermed in the trade.

An important object of myinvention is to provide a setting of acharacter to firmly hold the gem or other stone and at the same time tohave the effect of increasing the apparent spread of the gem materiallybeyond the actual spread thereof.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is a side elevation of a finger ring embodying my improvedsetting;

Fig. 2 is a plan view thereof;

Fig. 3 is a section taken through ting on the line 33, Fig. 2;

Fig. 4 is a section taken on the line 44,

the setfify improved setting for a ring 10 or other piece of jewelryincludes, as usual in settings, a plurality of cramps within which thegem A is to be mounted. In my invention the gem A is received in theopencenter of a frame 12 of special character. The frame 12 in thepreferred form is of starshape presenting pronounced star points andpresenting between the star points at the exterior of the frame recessesor depressions 13. The cramps 11 extend over the frame 12 at therecesses 13 and thereby alternate with the star points. In any event theframe 12 between and alternating with the depressions 13 will presentoutwardly projecting points or equivalent members affording effectiveholding engagement for the cramps and of a character to be givenornamental form such as star points or the like. Thus,

the arrangement provides for the secure mounting of the frame andesthet-ically the important result is obtained that the gem A whichactually is not set directly in the cramps appears except on closeinspection as if it were set directly in the cramps;

and the'apparent spread or area of the gem is increased beyond itsactual spread, because, for example, when the frame 12 is made of Whitegold, its frame character as distinct from the gem and cramps, is notinstantly apparent nor clearly obvious as its surface merges to the eyein the area of the gem.

The pressing of the cm A into the open center of the frame 12 gives asubstantial holding effect for the gem, but in addition,

inthe preferred form of my invention, I provide within the starpointsprongs 14 extending laterally inward to overlap the gem.

The mechanical form, and the utile function of the prongs 14 in holdingthe gem are actual, but their form and their character as. prongs arenot so pronounced but that esthetically they will be dominated by themajor lines ofthe star points and by the lines presented by thealternating cramps 11. In practice, the prongs 14, best shown in 3,advantageously are of a character to appear as if produced by displacingmaterial of the frame 12 at the outer surface and in an-inward radialdirection leaving corresponding depressions 15 outward of or at thebases of said prongs, an incidental advantage of this arrangement beingthat the prongs 14 and recesses 15 rather contribute to .givingprominence to the starpoint character of the members of the frame 12between the cramps 11 although reducing the apparent frame surface assuch.

Thus, by the described simple means I provide for the secure holding ofthe gem and at the same time obtain improved esthetic efiects with gemsof limited spread, the star shape of the frame particularly lendingitself to producing the apparent sprea I would state in conclusionthatwhile the illustrated example constitutes a practical embodiment of myinvention, I do not limit myself strictly to the mechanical detailsherein illustrated, since manifestly the same can be considerably variedwithout departure from the spirit of the invention as defined in theappended claims.

Having thus described my invention, I

projecting members at the periphery, said members being separated byperipheral depressions radially beyond which said members extend, saidcramps engaging said 5 frame at the depression thereof, thus alternatingwith said separated projecting members and being disposed about saidopening adjacent thereto.

2, A em setting including cramps, and a 10 frame tierein adapted toreceive the gem,

said frame presenting at the exterior alternating projecting members anddepressions, said cramps engaging said frame at the depressions thereofand thus ulternetin with said projecting members; together wit holdinprongs on the frame at the interior a apted to engage the gem, saidprongs being disposed between the cramps and at the ifiner sldes of theprojectin members.

MA BAUMAN.
